[R] Question about R performance on UNIX/LINUX with different memory/swap configurations

2012-09-16 Thread Eberle, Anthony
Does anyone have any guidance on swap and memory configuration when running R v2.15.1 on UNIX/LINUX? Through some benchmarking across multiple hardware (UNIX, LINUX, SPARC, x86, Windows, physical, virtual) it seems that the smaller memory machines have an advantage. Typically my organization
